Kansas Senate Race Exceeds Previous Spending Record

Ad spending in the Kansas U.S. Senate race has passed $84.5 million. This total makes it the most expensive election in the state's history. The figure comes from AdImpact, a data analysis firm tracking political advertisements.

The previous state record stood at $49.1 million during the 2020 election. That was the year Roger Marshall first sought the Senate seat. The current campaign has outpaced that benchmark by more than 70 percent. National attention has intensified as parties battle for control of the chamber.

Marshall faces Rev. Adam Hamilton, a pastor from the Kansas City area, and Libertarian candidate David Graham on Tuesday. Federal records show a sharp divergence in direct campaign spending. Hamilton's team has used over $16 million this season. Marshall's campaign has spent just over $6 million.

Outside groups drive the majority of the total cost. Spending by these entities has risen 3,332 percent compared to the 2022 Senate race. Pro-Marshall groups have aired ads worth more than $27 million. They have at least $8.5 million in reserve. Pro-Hamilton groups have spent over $34 million, with another $14 million expected to hit the airwaves.

The Senate Leadership Fund has spent at least $11 million supporting Marshall. The group moved money from North Carolina to Kansas earlier this month. On the opposition side, the People over Politics Action Fund has spent more than $11 million against Marshall. This Kansas-based super PAC has ties to former independent candidate Greg Orman, who donated $50,000 in July.

Lower Costs Now, a Democratic super PAC, has spent nearly $6 million against Marshall and $4.5 million for Hamilton. Main Street Fund, a Republican-affiliated group formed on primary day, has spent nearly $4.6 million against Hamilton as of October 21. The campaign has featured attacks on Hamilton's past sermons and Marshall's medical debt collection practices.
